The First Discharge of the Three Gorges Reservoir: A Precise Dispatch for the Safety of the Yangtze River Basin

Recently, the news of the first discharge of the Three Gorges Reservoir has sparked widespread attention. Many people are confused, believing that the middle and lower reaches of the Yangtze River are currently suffering from floods, and that the Three Gorges Reservoir should continue to retain water instead of releasing it. In reality, the discharge operation of the Three Gorges Reservoir is not simply "releasing water" but a flood control measure implemented after careful calculations and scientific dispatch, aiming to safeguard the safety of the Yangtze River Basin.

The Three Gorges Project: The "Steadfast Anchor" of the Yangtze River Basin

The Three Gorges Project, a significant water conservancy project in China, is much more than just a reservoir. The project comprises three main components: a dam, a hydropower station, and navigation facilities, with the Three Gorges Reservoir at its core. This artificial lake, with a total storage capacity of 39.3 billion cubic meters and a flood control capacity of 22.15 billion cubic meters, serves as the "steadfast anchor" of the Yangtze River Basin, playing a crucial role in the economic and social development of the region.

1. Transforming the Energy Landscape: A "Tower" of Clean Energy

The construction of the Three Gorges Project has fundamentally reshaped China's clean energy landscape. The Three Gorges Hydropower Station boasts a total installed capacity of 22.5 million kilowatts and an annual design generating capacity of 88.2 billion kilowatt-hours, providing robust energy support for China's "West-to-East Power Transmission" and "North-South Power Interconnection" initiatives. Over the past 20 years, the Three Gorges Power Station has generated over 1.6 trillion kilowatt-hours of electricity, equivalent to saving a significant amount of coal resources for the society and reducing carbon dioxide emissions by hundreds of millions of tons. It stands as a crucial milestone in the development of clean energy in China.

2. Smoothing the Waterway: A Vital Hub on the Yangtze Golden Waterway

The construction of the Three Gorges Project has significantly enhanced the navigation capacity of the Yangtze River, shaping a vital hub on the Yangtze Golden Waterway. The Three Gorges Ship Lock and the Three Gorges Elevator provide convenient and efficient navigation conditions for large vessels, promoting economic growth and cargo transportation efficiency in the Yangtze River Basin. In 2023, the Three Gorges Hub reached a record high in cargo throughput, exceeding 172.34 million tons.

3. Safeguarding Home: The "Guardian Deity" of Flood Prevention and Drought Resistance

The construction of the Three Gorges Project has effectively enhanced the flood prevention and drought resistance capabilities of the Yangtze River Basin, establishing a solid line of defense for tens of millions of people and millions of hectares of farmland in the middle and lower reaches of the Yangtze River. The completion of the Three Gorges Dam has raised the flood control standard of the Jingjiang section of the Yangtze River to a 100-year return period, effectively mitigating the risk of flood disasters in the middle and lower reaches of the Yangtze River. During the 2022 drought in the Yangtze River Basin, the Three Gorges Reservoir implemented joint dispatch, multiple times supplying water to the middle and lower reaches of the Yangtze River, alleviating the drought situation downstream and fully demonstrating its role as the "guardian deity."

The Strategy Behind Discharge: Scientific Dispatch to Ensure Safety

The seemingly simple act of "releasing water" actually conceals a scientific dispatch strategy and profound considerations behind it.

1. Freeing Up Storage Capacity: Preparing to Address New Floods

Although the Three Gorges Reservoir began intercepting rain in the middle and lower reaches of the Yangtze River in late June, continuous rainfall has caused the reservoir water level to rise continuously, nearing the warning line. It is crucial to free up flood control storage capacity to address potential larger flood peaks in the future. This discharge operation aims to control the reservoir water level within a safe range before the arrival of flood peaks, ensuring the safe operation of the Three Gorges Dam and preparing for new floods.

2. Staggered Discharge: Reducing the Impact of Flood Peaks and Easing Downstream Pressure

The discharge from the Three Gorges Reservoir is not a blind release of water. Instead, it is conducted after scientific calculations, choosing appropriate timing and flow rates for staggered discharge. By gradually increasing the outflow from the reservoir, the flood peak flow is dispersed over a longer period, reducing the impact of the flood peak on downstream areas and easing the flood control pressure downstream.

3. Circular Dispatch: Achieving Rational Control of Water Resources

The dispatch of the Three Gorges Reservoir is not merely about intercepting or releasing water. Instead, it involves dynamic adjustments based on hydrological changes, aiming to achieve rational control of water resources. The current discharge operation is part of the scientific dispatch of the Three Gorges Reservoir, aiming to ensure the safety and ecological balance of water resources throughout the Yangtze River Basin through "circular dispatch."

Scientific Response: Eliminating Misconceptions and Taking a Rational View

The first discharge of the Three Gorges Reservoir is a significant measure in flood control work in the Yangtze River Basin, a crucial means of safeguarding the safety of the region. We should rationally view this discharge operation and eliminate misconceptions about the Three Gorges Project.

1. Enhancing Publicity: Raising Public Awareness of the Scientific Nature of the Three Gorges Project

The construction and operation of the Three Gorges Project is an extremely complex system project, requiring scientific decision-making and management. To eliminate public misconceptions and enhance public awareness of the Three Gorges Project, relevant departments should strengthen publicity about the project, allowing the public to understand the project's construction philosophy, scientific nature, safety, and importance.

2. Respecting Science: Avoiding Attributing Extreme Weather to the Three Gorges Project

In recent years, global climate change has intensified, with frequent extreme weather events, causing some impacts on the Yangtze River Basin. However, it is unscientific and objective to attribute extreme weather to the Three Gorges Project. The construction of the Three Gorges Project has played a positive role in improving the ecological environment and flood prevention and drought resistance capabilities of the Yangtze River Basin and is not the culprit behind extreme weather events.

3. Working Together: Jointly Safeguarding the Ecological Security of the Yangtze River Basin

The ecological security of the Yangtze River Basin is crucial for the sustainable development of the Chinese nation and requires the joint efforts of the entire society. We should actively participate in the protection work of the Yangtze River Basin, starting from ourselves, reducing pollution to the Yangtze River Basin, and jointly safeguarding the ecological security of the region.

Conclusion: The Value of the Three Gorges Project Goes Beyond Flood Control

The Three Gorges Project is a significant landmark in the development of the Yangtze River Basin. It has not only brought substantial economic and social benefits to the region but has also effectively enhanced the flood prevention and drought resistance capabilities of the Yangtze River Basin, providing a guarantee for the ecological security of the region. The first discharge of the Three Gorges Reservoir is a reflection of the scientific dispatch of the Three Gorges Project, a crucial measure for safeguarding the safety of the Yangtze River Basin. It showcases the powerful capabilities of the Three Gorges Project and demonstrates the scientific nature and advanced level of China's water conservancy project management. With the continuous contribution of the Three Gorges Project, the Yangtze River Basin will undoubtedly usher in a brighter future.
